Queen Mary: Second Class Stairs 10

Rootsweb.com says, "The first sailing of what became the first regular transatlantic service between Great Britain and the United States was by the side-wheeler SIRIUS, chartered to the British & American Steam Navigation Co, which sailed from London on the afternoon of 28 March 1838, and from Cork at 10 A.M. on 2 April. She sighted land on the afternoon of 22 April, and anchored off the Battery, New York, early the next morning. A few hours later, she was joined by the side-wheeler GREAT WESTERN, of the competing Great Western Steamship Co, the first steamer built specially for the North Atlantic service, which had sailed from Bristol on 8 April 1838."
